Answer 2

Ответ:

x²+9x=0

x(x+9)=0

x1 = 0 x2 = -9

Answer 3

Solving the Quadratic Equation

To solve the quadratic equation x^2 + 9x = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0.

Applying the Quadratic Formula

In this case, the coefficients are: - a = 1 - b = 9 - c = 0

Using the quadratic formula, we can calculate the roots of the equation.

Calculation

x = (-9 ± √(9^2 - 4*1*0)) / (2*1)

x = (-9 ± √(81)) / 2

x = (-9 ± 9) / 2

So, the solutions for the equation x^2 + 9x = 0 are: - x = (-9 + 9) / 2 = 0 / 2 = 0 - x = (-9 - 9) / 2 = -18 / 2 = -9

Therefore, the roots of the equation are x = 0 and x = -9. This means that the equation x^2 + 9x = 0 has two real solutions, 0 and -9.
